Re: EnumThreadWindows - EnumThreadWndProc does not get called

I am using EnumThreadWindows to enumerate all windows of newly created
process using CreateProcess. EnumThreadWndProc gets called for notepad
but does not get called for MS Word. I am not able to figure out why it
is happening, Here is piece of code.

STARTUPINFO si;
PROCESS_INFORMATION pi;

ZeroMemory( &si, sizeof(si) );
si.cb = sizeof(si);
ZeroMemory( &pi, sizeof(pi) );

   // Start the child process.
   if( !CreateProcess( TEXT("C:\\Program Files\\Microsoft
Office\\OFFICE11\\winword.exe"), NULL,NULL,NULL,FALSE,FALSE,0,NULL,NULL,&si,&pi
)
   )
   {
       printf( "CreateProcess failed (%d).\n", GetLastError() );
       return;
   }
   Sleep(10000);
   WaitForInputIdle(pi.hProcess,10000);

   // Enumerate all threads of Windows
  BOOL bRetVal =
EnumThreadWindows(pi.dwThreadId,EnumThreadWndProc,(LONG)this);

  if(! this->m_hWnd )
  return;

BOOL CALLBACK EnumThreadWndProc(HWND hwnd,LPARAM lParam)
{
     CMainFrame *pFrameWnd = (CMainFrame*)lParam;
     if(GetMenu(hwnd) != NULL)
     {
  pFrameWnd->m_hWnd = hwnd;
    return FALSE;
     }
   return TRUE;
}
